Explanation:
x>2" is in solution form"x>2 is in solution form and tells us that x cannot equal 2 but can take values greater than 2.
"this is expressed in interval notation as "(2,+oo)this is expressed in interval notation as (2,+∞) The parenthesis on both ends of the interval indicates that x cannot equal
2" or "+oo2 or +∞ but any value in between them.
"If the solution was "x>=2" then"If the solution was x≥2 then
[2,+oo)[2,+∞) would be the solution in interval notation.
"the "[" indicates can equal the value at this end."the [ indicates can equal the value at this end.
